Well, you can have as may printer adapters as yopu like if you can set
them all to different addresses and if you're writing your own software
to talk to them...
Naturally. The problem I see is that only the older cards might let
you set the printer port to respond to arbitrary addresses - the ones
I have are almost (entirely?) all of the style where you move a single
jumper for LPT1 vs LPT2 (primary vs secondary address).
I wasn't as worried about the OS interpretation since I don't intend
to *print* to my printer port.
